f7a1f28d7f Kernel: Add initial basic support for KASAN
This commit adds minimal support for compiler-instrumentation based
memory access sanitization.
Currently we only support detection of kmalloc redzone accesses, and
kmalloc use-after-free accesses.

Support for inline checks (for improved performance), and for stack
use-after-return and use-after-return detection is left for future PRs.

20162874e0 Toolchain: Use nixos-unstable instead of nixpkgs master in flake
This patch updates the flake to track the nixos-unstable branch instead
of master for the nixpkgs flake input.

This ensures that hydra.nixos.org (the NixOS CI) has built all packages,
made them available in the cache.nixos.org binary cache without the risk
of a definitions (evalulation) being broken on master.

2cb977e368 Toolchain: Actually compile the GN binary in BuildGN.sh
The gen.py script only generates the build.ninja file for GN. We have to
explicitly build it afterwards.

This also sets the executable bit on BuildGN.sh.

4defa401d3 Toolchain+Ports: Update binutils to 2.41
Aside from a straightforward rebase, this contains an out-of-tree patch
from MaskRay which adds the `-Bsymbolic-non-weak-functions` flag to ld.

ae21002cb5 Toolchain+Ports: Update GCC to 13.2.0
This is a minor bugfix release, which to my knowledge contains nothing
of importance to us. However, there is one QoL change to our patches.

We no longer force `-fpic` in the compiler driver, and instead use the
`--enable-default-pie` configure option to generate position-independent
code suitable for executables. For building shared libraries, the
`-fpic` flag must be specified explicitly.

patches aren't needed anymore.

f46b393d2d Toolchain: Add Toolchain/nix-profiles/ to .gitignore
Let users save their nix develop derivation in a profile by ignoring
this specific folder. It encourages the following workflow:

```
nix develop Toolchain/ --profile Toolchain/nix-profiles/dev
```

Which stops the dev enviornment being collected in the nix store. Later
devs can come back and do:

```
nix develop Toolchain/nix-profiles/dev
```

To continue where they left off, without having to download everything
from nixpkgs again.

0124d731ce Toolchain: Remove xlibswrapper and add python3 to serenity.nix
xlibswrapper is removed from `Toolchain/serenity.nix` as it is a
wrapper package and has been deprecated. We don't use it in the build
anyway.

This fixes #19286

During the build, python3 is required so we add `python3` as a build
dependency.

47e0ea8e42 Toolchain: Add nix flake
Add a nix flake to `Toolchain/` that wraps the existing nix derivation
`Toolchain/serenity.nix`. This also comes with a lockfile making the nix
developer enviornment setup more reproducible.

We also update the documentation for "other builds" to mention the
flake.

We were previously missing `Kernel/Arch`, which gets included by
`Kernel/API`.

While at it, remove `AK` from the list of copied headers for the
toolchain, as nothing in our LibC headers should ever publicly depend on
AK.

6bcd73a2ff Toolchain: Disable libstdc++ PCH compilation
These are not useful for us, and unnecessarily waste time when building
the toolchain. Even if we used libstdc++ more heavily, our use of
uncommon, PCH-affecting flags and our frequent LibC header changes would
make these ineligible for use anyways.

built-in compression (which is zstd, I believe).

02fe3feb71 Toolchain: Enable RELRO support for AArch64
The BFD linker requires the `COMMONPAGESIZE` emulation parameter to be
set in order to enable RELRO support for AArch64. As we are adding a
custom `emulparams` file anyways, let's also tell LD that our ELF
interpreter is called `/usr/lib/Loader.so`.

This commit also removes some vestigial references to i686 SerenityOS.
The one in `gas/configure.tgt` is still needed, as it also handles
x86_64.

This is a mostly straight-forward rebase of our patches on top of
13.1.0. The spec files needed a change, as GCC no longer supports STABS
debug information, but we were building GCC with support for it.

Highlights of this release include static `operator()`, The Equality
Operator You Are Looking For and extended `constexpr` support.

4c2ad70066 Toolchain: Use ninja to bootstrap CMake
For some reason (for me) on Ubuntu 22.04 the standard make generator
fails:

  ---------------------------------------------
  CMake has bootstrapped.  Now run gmake.
  make: make: Permission denied
  make: *** [Makefile:166: all] Error 127

This seems to be because Source/kwsys/CMakeFiles/cmsys.dir/depend is
missing or not generated. Using ninja works fine though, and as it is
already the default for Serenity proper, it seems reasonable to switch
it here too.

a7f61a15af Toolchain: Fix self-built QEMU crashing on startup on macOS
If the SDL libraries are present on the system, QEMU will attempt to use
that for rendering the UI. This causes a crash when the AArch64 port
starts up with the following message:

> NSWindow drag regions should only be invalidated on the Main Thread!

Fix this by explicitly disabling SDL support.

- QEMU_ARCHIVE           - Filename
- QEMU_ARCHIVE_URL       - Full url to download location

5ca1bd55a0 Toolchain: Move GDB build to a separate script
Target GDB is only used for debugging the kernel, which is not relevant
to most people. Starting with 924758c6f8, GDB would always be built
as part of the toolchain if the user didn't have it installed. This is
unnecessary.

This commit adds a separate script for building GDB, which the user
needs to explicitly invoke. A message is added to Meta/debug-kernel.sh
which alerts the user to this fact.

924758c6f8 Toolchain+Meta: Support kernel debugging with host AArch64 GDB
Previously, we would unconditionally build GDB from source for the

`gdb` binary if it supports the architecture, or `aarch64-elf-gdb` if
such a package is installed.

An `aarch64-elf-gdb` package will be available through Homebrew once
